Comparison of the sensing mechanisms and capabilities of three functional materials surface-modified TFBG sensors

Three functional materials were coated on tilted fiber Bragg grating (TFBG) sensors, and through the analysis of the characteristics of TBFG sensors’ amplitudes in the core and cladding modes, their abilities to sense humidity were compared. The mechanisms by which physical moisture absorption sensi...
